SteganoG v1.30

billon on 6 Apr 2017

SteganoG hides an encrypted file inside a image file (BMP or RAW) and acts as a carrier. Also known as steganography, the program offers a variety of encryption algorithms including Blowfish, TEA, and Twofish.

Note that the included Skipjack and RC4 algorithms have known weaknesses.

Does not seem to decrypt properly when using blowfish. I am unsure if it is the encrypt of decrypt side that is causing the issue. RC4 encryption works perfectly.

Does not encrypt/decrypt properly with all methods, but RC4 works fine. When CompressData is enabled, the decrypted file is smaller sized. When CompressData is disabled, the decrypted file seems to be the correct size but it is not the original file (checksum mismatch/content unreadable).

Hyper Crypt v1.5.7.0

billon on 3 Jul 2017
  • 2MB (uncompressed)
  • Released on 4 Nov 2016
  • Suggested by Orca

Hyper Crypt allows file, folder, and text encryption, as well as file hashing and key/password generation. Files encrypted are renamed with "_enc" addendum, while folders are not renamed. The program can encrypt files using AES-256, RSA (asymetric / public key), and One-Time Pad. Hashing includes SHA-1, 256, 384, 512, and more.

gpg4usb v0.3.3-2

webfork on 23 May 2018
  • 29MB (uncompressed)
  • Released on 5 Jan 2016
  • Suggested by gpg4usb

NOTE: This project is outdated and may be insecure or incompatible with more recent versions of GPG.

---

gpg4usb is a basic, tabbed notepad tool with easy-to-use text and file encryption tools. Using the Gnu Privacy Guard (GPG) security system means you can exchange encrypted text and files with someone you've never met, where most programs require a communicated password. Additionally, users can digitally "sign" and verify information to help establish integrity, ownership, or agreement.

Users need only exchange a "public key" with one another in order to communicate. New users will need to generate a key, while users of other compatible software can import their existing keys.

Functional in Linux (see How to Extract). GPG is a compatible, open source alternative to commercial PGP.

Hello,

In the last week we integrated 4 new languages.

@procyon: Thanks for the hint, we've put it on our bug list and already located the appropriate line in source, which causes this bug. So this will be fixed in the next release.

@mixture: We weren't sure, if we should integrate this, because it could confuse beginners, who read in other tutorials, that the should use the maximum keysize possible. Would be great, if you write your opinion to our mailing list. In fact we're not sure, if we should reduce the maximum key size again to 8192 (which is the maximum key size of any other gpg program We know).

@webfork: We've already integrated generation of RSA keys for the next release. So this will be possible soon. And the size of the DSA key is always 1024 bit (given by gpgme I think), the size of the EL Gamal subkey can be set higher...

gpg4usb 0.3.2-1 released today!

0.3.2-1 generates safer gnupg-keys by default, with RSA and 1024bit minimum.
Including gpg binary was updated to version 1.4.12.

Bugfix:
Fix creation of empty Windows registry key on import from existing GnuPG

Have fun! http://gpg4usb.cpunk.de/

gpg4usb on 2014-08-20 20:22

New stable release 0.3.3-1

* gpg4usb-0.3.3-1 additionally contains a 64-bit linux binary now, so there's no need to have 32-bit compatibility libraries installed on a 64-bit linux system anymore

* we updated the included GnuPG-binaries from 1.4.16 to 1.4.18 for fixing some security issues

New alpha release 0.4

This release additionally contains binaries for MacOS. But since we had to rewrite the whole core, this release needs a lot of testing. So, if you want to be sure, better get the stable release. If you want to have a look what is planned for the release when it is finished have a look on our TODO-List.

Drag'n'Crypt ULTRA v2.3.9

webfork on 28 Feb 2017
  • 652KB (uncompressed)
  • Released on 20 Jan 2015
  • Suggested by Fluffy

Drag'n'Crypt ULTRA is a small file encryption tool that uses a handy "drop box" interface to make encryption and decryption fast and easy. Uses the Twofish encryption algorithm

Note:

  • File size is limited. Maximum file size depends on 1/2 free memory (for example: with a RAM of 512 MB RAM you can encrypt a 256 MB file). The author recommends TrueCrypt for larger files.
  • The website is in German, but the program is in English.
  • Starting from version 2.2.0, Drag'n'Crypt ULTRA is no longer backwards-compatible with data encrypted using Blowfish or TEA.

VaultPad v1.2

webfork on 2 Nov 2016
  • 988KB (uncompressed)
  • Released on 7 Dec 2014
  • Suggested by kitsaros

VaultPad is a simple text and file encryptor. The program can take text, attachments, or both to create an easy-to-share XML file for storage or sharing.

The program uses AES cipher (symmetric-key pairs) to encrypt local messages and RSA/AES cipher (public/private key pairs) for shared messages. A SHA-512 cipher is used to hash passwords, so they aren't stored in the application itself. A MD5 algorithm is used to check embedded files for corruption. VaultPad will handle third party public keys to be able to encrypt/decrypt their files directly.
